The High Court judge hearing a challenge against the Government's Three Waters by the Whangārei District Council has reserved her decision.
Justice Jill Mallon has reserved her decision in the case brought by the Whangārei District Council (WDC) with the Timaru and Waimakariri District Councils against the Government, seeking independent declarations related to property ownership rights.
The matter was heard in the court on Tuesday and Wednesday this week and the decision will be released at a later date.
Whangārei Mayor Sheryl Mai said the future of her district's $1.34 billion of ratepayer-funded drinking water, stormwater and wastewater assets rested on the decision.
She said the independent declarations sought were about clarifying fundamental principles of property ownership and democracy.
